What is a ‘kudo’? According to the Taxpayers’ Alliance, it is a mark of honour, many of which should be given to the Commons’ British Infrastructure Group, for demanding the scrapping of Air Passenger Duty.

The Alliance clearly thinks that ‘kudo’ is the singular of our ‘kudos’. It is not. Kudos is singular already: it has been brought into English from ancient Greek κυδος (‘glory, honour’).
